Key points of process control when smelting cast iron in induction melting furnace

The key points of process control when it is recommended to use індукцыйная плавільнай печ to smelt cast iron are as follows:

1. The amount of pig iron ingots in the charge should not exceed 20%, preferably around 10%;

2. In the recarburizer added with the charge, it is best to have a certain proportion (40-55%) of metallurgical silicon carbide;

3. Carefully carry out the inoculation treatment during iron tapping, and select appropriate inoculants according to the specific production conditions of the enterprise. The amount of inoculants added should be 0.1-0.2% higher than that during cupola smelting. The best amount should pass the field test results. Sure;

4. Must be incubated instantaneously during the pouring process;

5. When producing castings with high quality requirements, metallurgical silicon carbide should be added to the furnace for pretreatment before tapping.
